Specification of Letters'Patent. I Patented April 27, 1909.

Applioation med August 12,1908. Serial No. 448,085;

phia, and State of Pennsylvania, have invented a new and usefulImprovement in Semi-Convertible Cars, of which the following is aspecification.

The object of my invention is to provide a car of the so-calledsemi-convertible type, particularly suitable for high speed service,

and it has more particularly for its object a.

sash and post construction by means. of which anupper sash may be movedindependently of a lower sash so that the car window may be openedeither at its top or bottom, as desired. This object is accomplished bymy invention as detailed below.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which:

Figure'l is a sectional elevation showing a stanchion and the sashadjacent thereto in their closed position. Figs. 2 and 3 are sectionalviews taken on the lines 2-2 and 33 respectively, of Fig. 4, looking inthe direction of the arrows. Fig. 4 is an enlarged view of the structureshown in Fig. 1 near the line 2-2. Fig. 5 is similar to Fig. 4 exceptthat the view is taken near the line 33. Fig. 6 is a detailed viewshowing a portion of the lower sash.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved car 1 is provided with the usual stanchions 2 whichareconnected by the window sill 3 and letter boards 4, and by the roof 5,deck rail 6, head-lining 7, and molding 8, all of which may be of theconventional form except for the differences hereinafter noted. Thestanchion 2 also has the usual parting strips 2 and 2, inside andoutside respectively. The stanchion .(only one is shown) 2 is providedwith pintle grooves 9 and 10 respectively. The intlegroove 9 extendsfrom a point below t e letter board 4 in an upwardly andinwardlyundulating direction to a point near the roof 5 and over themolding 8. This pintle groove 9 is shaped substantially as shown inFigs. 1

and 2 so as to conform to the structure of the car.

The upper sash 11 is provided on its side frames. with suitablepintles12 located near its upper edge and which slide in the groove 9- therebydetermining the movement of the upper end of that sash. The lower edgeof the sash is provided with a sliding bolt 13, which is adapted toenter special holes formedin the base of the groove 9 in theconventional manner, so as to support the sash in any of severalpositions. The up er one of these holes is. shown in dotted ines in 4.

The lower sash 14 overlaps the up or sash 11 in the conventional manner,and is pro vided with a sliding bolt 15 near its lower edge mounted asusual, near the hand lift 16, and a bolt actuating handle 17. This sash14 near its u per edge is provided with a pintle 18 that s ides freelyin the pintle groove 10. The pintle groove 10 is preferably shaped asshown in Fig. 1, its upper end terminating in the enlargement 19, inwhich only the lower edge 20 is operative when the sash 14 is raised,its lower end terminating at the sill 3. When the sash is'lowered thepintle 18 is shifted from the lower edge 20 to the groove 10, as isobvious. The pintle 18 may be of any. suitable construction. Heretofore,the pintles sliding in grooves have been mere pins or projections,sometimes provided with a bushing or sleeve to act as a roller.v Thepintle 18 preferably consists of a plate 21 from which extends the ear22 on which a shoe 23 is pivotally mounted. The shoe 23 has a surfaceadapted to rub against the inner wall of the groove 10 and the edge 20whereby a large Wearing surface is utilized so that the wear on thesides of the groove 10 is reduced to a minimum.

The stanchion 2 is preferably recessed at 24 to receive a metalwear-plate (see Fig. 3) against which the shoe 23 rests when the sash14'is in its lowest position, so that the sash 14 is forced positivelyand firmly against the upper sash 11 whereby a close joint ismaintained. Below the wearlate 25 the groove 10 is extended downward yand outwardly so as to be in the plane of the sash. 14. The base of thegroove 10 is provided with any number of suitably located holes for thebolt 15.. These are located as may be convenient, one being placed at 26as shown in Fig. 4 to receive the bolt 15 when the sash is in its mostelevated position, and another at 27 for an intermediate position.

In the construction above described each sash may be raised and storedunder the roof; and lowered independently of the other sash, therebysecuring great flexibility of disposition of the sash for ventilation.

be opened from the inside of the car without raising the lower sash 14so that the bolt 13 can be reached.

While I have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto but is broad enough to coverall structures that come within the scope of the annexed claims.

That I claim is: r

1. In a car, a plurality of sashes, stanchions having independentpintlegrooves, and sashes with pintles entering said grooves, so thatone sash may be raised or lowered independently of the other, one ofsaid pintles bfiing provided with a pivotally mounted s 0e.

2. In a car, stanohions, upper and lower sashes, pintles near the upperedge of said upper sash adapted to move in one of said pintle ways, andpintles and bolts on the lower sash adapted to move in the other of saidpintle ways, the pintles of the lower sash being provided with pivotallymounted shoes.

3. In a car, stanchions, upper and lower sashes adapted to slide betweensaid stanchions, pintle ways in said stanchions, pintles on said sashes,one of said pintles being provided with a plate, an ear, and a shoe piv-3 oted to said ear. It is obvious that the upper sash 1 1 cannot 4. In acar, stanchions having independent pintle grooves above the letter-boardone of which extends in an upwardly and inwardly undulating direction,and sashes with pintles entering said grooves and movable entirelyindependently of each other.

5. In a car, stanchions having independent pintle grooves above theletter-board one of 'hich extends in an upwardly and inwardly undulatingdirection, sashes with pintles entering said grooves and movableentirely independently of each other, the pintles of the lower sashbeing provided with pivotally mounted shoes.
